GRATER.

Specification of Letters Patent.

Patented Oct. 8, 1907.

Application filed July 21,1906. Serial No. 327,196.

To all whom it may concern:

Be it known that I, HERMENIA VAN DER Voonr, of the city of Toronto, in the county of York, Province of Ontario, in the Dominion of Canada, have invented certain new and useful Improvements in Graters; and I hereby declare that the following is a full, clear, and exact description of the same.

The invention relates to improvements in graters as described in the present specification and set forth in the accompanying drawings that form part of the same.

My invention relates to improvements in graters and the object of the invention is to devise a grater which shall insure the separation of the lump of sub stance into fine particles without handling the said lump during the operation of grating, and whereby.

the cost of production of such devices is not materially increased, and it consists essentially in arranging a grating surface on the face of a disk, and in providing the means for rotating said disk, and supporting the substance to be grated in proximity to said grating surface, as hereinafter more particularly explained in the detailed description of the various parts.

Figure 1 is a perspective view of my device. Fig. 2 is a perspective detail of the grater disk. Fig. 3 is a perspective detail of the gripping or feeding device. Fig. 4 is a modification of my device as applicable in large kitchens.

Like letters of reference indicate corresponding parts in each figure.

Referring to the drawings a is the upright portion of the frame'of the device and b is an arm extending at a right angle from the lower end of said upright.

c is an arm extending laterally from the upright at intermediate of its length and forming with the arm' b a jaw d to fit over the edge of a table or bench where it is, desired to use the device.

The arm b is enlarged at its outer end forming a boss e, and f is a vertical threaded orifice through the said boss. 7 is a thumb screw correspondingly threaded to the orifi'ce f and fitting therein and having at the lower end a suitable wing portion h to facilitate the turning thereof.

1' is a washer secured to the upper end of the screw g forming a large bearing surface on the end of the screw and also preventing the entire withdrawal of the screw from the orifice f.

j is a boss formed at the upper end of the upright a having a horizontal circular orifice 7c therethrough forming a journal bearing.

l is atable secured to or forming part with the upright a at its upper end and extending laterally therefrom. The table 1 extends horizontally and preferably to one side of the vertical center line of the upright c and is supported from said upright by the Web or bracket m.

n is a lug projecting downwardly from the table Z at the outer end thereof and having a circular orifice 0 therethrough forming a journal bearing in alinement with the journal bearing is.

p is a shaft journaled in the bearings 70 and 0, and q is a suitable crank fixedly secured thereto at the end in proximity to the upright a.

r is a disk fixedly secured to the outer end of the shaft p having a plurality of grating teeth 8 projecting from its inner face, the said disk being so arranged on the end of the shaft 7) that the projecting teeth will pass the outer end of the horizontal table t when the disk is rotated.

t are flanges extending upwardly from the side edges of the table I and preferably partly overhang the surface of the said table. s

u is a feed plate having the fiat portion 1) adapted to rest upon the surface of the table and the upright portion w forming a face which is adapted to abut the material placed upon the table to be grated. The face of the portion in may be provided with suitable teeth or projections to grip the material and prevent it from being tipped upwardly by the action of the grater. The edges of the feed plate a are preferably sloped outwardly as shown so that they will extend into the recesses formed on either side of the table by the overhanging edges of the flanges t, thus retaining the plate securely in position and preventing it from being lifted in an upward direction but at the same time allowing the said plate to move freely in a longitudinal direction.

In Fig. 4 a modification of the device is shown which is applicable for use in large kitchens where large quantities of materials are used. as is the table top having a cross slot y in proximity to one end thereof. 2 is the grater disk fixedly secured to one end of the shaft 2 which is journaled in suitable bearings preferably arranged below the said tabletop, and 3 isapulley fixedly secured to the outer end of the shaft 2 which may be rotated by a suitable belt in connection with a suitable source of power. It must be understood that the shaft 2 may be provided with a crank to be driven by hand or a suitable crank and foot treadle might be substituted in order to drive the grater disk. 4 is a casing surrounding the grater disk below the table top at to prevent the disk being injured and also to form a guide for the grated material to lead the same to a suitable drawer 5 provided at the bottom of said casing to receive the said grated material.

In the operation of a device such as described the grater disk is rotated in any suitable manner and at any suitable speed to suit the requirements of the substance to be grated and the said substance is placed upon the table and pushed against the moving face of the said disk. The grater teeth on the face of said disk come in contact with the lump of substance and cut into the same separating it into fine particles which fall from the face of said disk downwardly into a suitable receptacle.

In the smaller form of the device the feed plate a is pressed against the lump of substance and the teeth or projections on the face prevent the substance being grated from tipping upwardly through the downward action of the grater disk, and also enables the person operating the device to feed the lump close up to the grater disk without being in danger of injuring the fingers by accidentally coming in contact with the grating surface and also insures the grating of the last particle of the lump, which is a great advantage. The use of a feed plate is also very desirable for cleanliness, as it obviates the necessity of the operator soiling the fingers while grating.

What I claim as my invention is 1. A grater, comprising an upright or standard having a lateral extension therefrom at its extreme upper end forn1- ing a table and a journal orifice below said extension, said table having longitudinal upwardly extending flanges from the sides thereof forming guide-ways and a lug depending from one corner thereof having a journal orifice in alineinent with the aforesaid journal orifice, a shaft extending through said journal orifices beneath said table, a grater wheel secured to the end of said shaft in prox imity to said table, means for rotating said shaft secured to the other end thereof, and a feed plate sliding between the aforesaid flanges having an upright portion thereto and a roughened face to said upright portion, substantially as described.

2. A grater, comprising an upright arm having a vise hold at the lower end thereof and a journal orifice at the upper end, a table having suitable guide-ways thereon rigidly supported by and above the said upright arm by a suitable bracket therefrom a journal bearing supported by said table in alinement with the aforesaid journal orifice, a shaft turning in said bearings, a grater whee] secured to one end of said shaft in proximity to the end of said table and a crank handle secured to the other end, a feed plate having a flat portion sliding between the aforesaid guideways and an upright portion having its inner face roughened to grip the material to be grated, substantially as described.

Signed at the city of Toronto, in the county of York, Province of Ontario, in the Dominion of Canada, this 26th day of June, 1906.
